In such dye-focused methodologies, the matrix plays a minimal role beyond hosting the emitters. However, this strategy can be unpredictable due to the complexity of modifying dye photophysics with precision. In the work here presented, a matrix-driven approach to WLE is introduced, where the properties of the polymeric host are leveraged to regulate light emission. By adjusting the composition of the polymer network with variation in monomers and cross-linkers, it is possible to control the spatial arrangement and interaction of two dyes, enabling effective color mixing. The system employs readily available monomers, 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) dimethacrylate (PEGDMA), along with two simple, synthetically accessible dyes: a pyridinium salt and a pyrylium derivative. The resulting hydrogel-based films emit white light with Commission Internationale de l'Éclairage (CIE) chromaticity coordinates at (0.30, 0.33) and a high photoluminescence quantum yield of 0.51. The films are highly transparent, flexible, and suitable for back-illumination, making them excellent candidates for integration into next-generation optoelectronic platforms, such as bendable lighting elements, transparent displays, and wearable light sources. This strategy highlights the untapped potential of polymer matrices in fine-tuning emissive behavior.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501380","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, optimizing charge carrier injection and transport remains a challenge. Efficient electroluminescence requires a balanced transport of both holes and electrons within the emitting material. Here, cubic CsPbBr3 nanocrystals passivated with oleylamine and oleic acid are investigated, comparing them to ligand-exchanged nanocrystals with didodecyldimethylammonium bromide (DDABr). Nuclear magnetic resonance spectroscopy and transmission electron microscopy confirm successful ligand exchange, revealing reduced ligand coverage in DDABr-treated nanocrystals. Photoelectron spectroscopy, spectroelectrochemistry, and single-carrier devices indicate improved hole injection in DDABr-capped nanocrystals. Density functional theory calculations further reveal the influence of ligand type and coverage on energy levels, with oleic acid introducing localized states in native nanocrystals. Additionally, incorporation of a polar electron transport layer enhances LED performance by over an order of magnitude in DDABr-capped nanocrystals, driven by improved charge balance arising from the spontaneous orientation polarization of the electron transport layer. These findings highlight the critical role of ligand selection, passivation degree, and charge transport control by the adjacent organic transport layers in optimizing LED efficiency.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501361","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a mini-spectrometer that combines a large-scale radiative cavity array with end-to-end deep learning networks is proposed and demonstrated. Specifically, high-Q bound states are utilized in continuum cavities with distinct radiation characteristics as the fundamental units to achieve parallel spectral detection. An array of resonators with quality factors above 104 over a wide spectral range, from 1525 to 1605 nm, is realized. A deep network with 8000 outputs is further trained to directly map arbitrary spectra to array responses excited by the out-of-plane incident.

Most of the polymorphic crystal phases of this semiconductor belong to the family of 2D van der Waals semiconductors. In this study, optically active indium selenide crystal phase heterostructures are fabricated by molecular beam epitaxy in a well-controlled manner. It is demonstrated that by changing the growth conditions one may obtain either γ-InSe, or γ-In2Se3, or β-In2Se3 crystal phases. The most promising crystal phase heterostructures from the point of view of photonic applications is found to be the γ-InSe/γ-In2Se3 heterostructure. An intense optical emission from this heterostructure appears in the near infrared spectral range. The emission energy can be tuned over 250 meV by changing γ-InSe layer thickness, which is explained by the quantum size effect. The optically active indium selenide crystal phase heterostructures represent, therefore, an interesting platform for the design of light sources and detectors in the near infra-red. The use of molecular beam epitaxy for this purpose ensures that the structures are fabricated on large surfaces opening the possibility for the design of device prototypes by using lithography methods.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 26","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145051257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of VPCs is typically based on analogies with condensed-matter topological insulators that exhibit the quantum valley Hall effect; trial-and-error approaches are often used to tailor the photonic band structures and their topological properties, which are characterized by the local Berry curvatures. In this paper, an inverse design framework based on frequency-domain analysis is presented for VPCs with arbitrary pseudospin states. Specifically, the transverse spin angular momentum (TSAM) at the band edge is utilized to formulate the objective function for engineering the desired topological properties. Numerical experiments demonstrate that the proposed design approach can successfully produce photonic crystal waveguides exhibiting dual-band operation, enabling frequency-dependent light routing. The pseudospin-engineering method thus provides a cost-effective alternative for designing topological photonic waveguides, offering novel functionalities.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
